To all 'whom it may concern:

Be it known that l, lViLLIAM F. BUTLER, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Machines forApplying Cement to Gan-Caps, of which the following is a specification.

In the use of cans or packages of a certain type, a liquid orviscouscement is placed between a portion of the main body of the can orpackage and a portion of the cover before the cover is arranged in finalposition.

The object of my invention is to produce an efficient apparatus toautomatically ap: ply such cement or sealing material.

The accompanying drawings illustrate my invention. 1

Figure 1 is a plan of a machine embodying my invention; Fig. 2 anelevation in partial vertical section; i0'. 3 a section on line 3-3 ofFig. 2; Fig. 4 a detail section on line 4-4 of Fig. 2; Fig. 5a similarsection on line 5 5 of Fig. 2; Fig. 6 an enlarged sectional detail of aneffective form of delivering means for the cement; Fig. 7 a similarsection at right angles to Fig. 6; Fig. 8 a detail ofa part of the capfeeder; Fig. 9 a section of a' can or package ofthe character referredto, and Fig. V10 an elevation, in partial vertical section, of amodified form of machine embodying my invention.

In the drawings, Figs. 1 to 8 inclusive, 10 indicates a suitable mainframe comprising a feed table 11, inwhich, between Suitable guides 12,is arranged a feed slide 13. Journaled in frame 10 -is a main driveshaft 14 provided with a crank 15 connected to the feed slide by a link16. Arrangedin 2the' delivery end of table 11 is a rotary table 17carried at the upper end of a shaft 18 connected by a pinion 19 and agear 20 with shaft 14, the gears being so proportioned that table 17Will be turned comparatively rapidly and preferably at least threecom.-.

plete rotations each actuation, for a purpose which will appear. Theupper face of the table 17 is even withthe face of table 11 and isprovided with several concentric grooves 17 iso-facilitate the centeringof caps 21- of different sizes each of said caps having an annulargroove 22A for the reception of a thin layer of cement 100.

Arranged above tablel? is a cement delive ering spout, 25 which may beadjusted toward and from the axis of table 17 So as to aline with thecement-receiving grooves of caps of various sizes, lsuch adjustmentbeing accomplished, in the present machine, by

,bolt 26 passed through slot 2T .of the supporting arm 28. Spout 25 iscarried vby a' pump body 29 having a chamber '30 communicating with theinterior of the spout. Intersecting chamber 3() is a passage protectedat each end by a packing gland 31, and' in which yis mounted a valve 32having a passage 83 adapted to aline with chamber 30. Mounted in thepump body 29, and alined with chamber 30, is a pump piston 34 connectedby a link 35 with a block-36 adjustablymounted Ona lever 37 parallelwith d the lineof adjustment of the spout 25. Lever 37 is connected by alink 38 with a lever 39 actuated in both directions by a cam 40 carriedby a shaft 41 connected by a 75 suitable driving-chain 42 with shaft 14,so as to be rotated in unison with shaft 14. u

Leading into the side of the passage in which valve 32 is mounted is, aninlet passage 44 which communicates with a cement reservoir 45 through atube 46 the arrangement being such that cement may flow freely from thereservoir into the pump cylinder. Reservoir 45 is mounted suitable ways47 so that it may partake` of the adjustment of the spout and4 pump and,in order to keep the cement in good. condition, I provide a stirrer 4Scarried by a shaft 49 having a crown-friction wheel 49 on its lower endadapted tobe engaged by a cylindrical friction wheel 50 carried by shaft14.

In order toprevent waste of cement, and to keep table 17 clean, when nocap is in proper position to receive the cement I provide, centrallyabove table 17, a plunger or= holder 51 normally urged'downward towardthe table 17 by means of a spring 52. Connected to plunger 51 is a lever53 by means; of which the plunger may be lifted against the action 'ofspring v52, the said lever having one endy arranged .in the path ofmoveli'nent of a cam l54 carried by shaft 41. Valve andbrixig theL-shaped passage 58 of the.

- cam 69 valve into alinement with the pump cylinder and the inlet 44(Fig. 7 1When the valve is in the position just mentioned, a notch 59,in the outer end of valve 32 lies in alinemeut with a locking bar 60connected by alink 61 with the upper end of plunger 51.

In order to feed the caps to the table 17 and remove the .same therefromafter the cement has'been applied, I provide the following mechanism. p'Slide 13 is provided with a capreceiving notch 65 at its forward end, towhich the caps may be successively fed through the common feed chute(not shown) .and the stroke of theslide is siiiii'- cient to carryeachcap from such chiite to the table 17. In lorder to prevent'tiltingof the caps l deem it advisable to displace ,a treated cap by meansNother than the oncoming ycaps and for this purpose provide slide 13with a forwardly extending arm 66 which', at its forward end carries apivoted usher finger 67 adapted to lie projected into the'path ofmovement of the oncoming caps or tolie retracted-therefrom. Finger 67carries a piny68 adapted to engagea stationary cam or "guide 69 arrangedaloiigits path of movement. At the forward end of is a pivotedspring-pressed guide finger 70 and at the rear end of said cam is aguide finger 71 similar to finger 70 but reversely positioned. i v iWith the parts inthe positions shown in the drawings one. rotation ofshaft l14 in fthe direction indicated in Fig. 3 will cause threecomplete rotations of table 17 and a down-stroke of piston 34 so as toforce a stream of cement into the groove 22 of cap 21. Piston 34 andplunger 51 then move upward and slide 13 moves forward bringing inger 67into engagement with the cap on table 17 and carrying it over into thedischarge chiite 72,v a newcap being, at the same time, driven forwardbyslide 13 and deposited on the table 17 where it is readily` centeredby the appropriate groove 17 Cam 54v now permits plunger 51 to descendAupon the freshly placed cap on table 17 and said plunger, resting onthe cap, prevents the loclr-bar v from descending low enough to enternotch 59, valve 32 being at this moment held in the position shown inFig. 7, by cam 57 but quickly returned to the position shown in Fig. 6.Slide 13 thereupon returns and, pin 68 engaging iinger 71, the finger 67is swung into line with arm 66'(see Fig. 8) 'so as not to engage orinterfere with the newly placed cap on table Y 17. At the same timetable 17 is rotated by gears 19 and 20, vand pump plunger 34 drivendownward by'cam 40 so as to deliver k.a stream of cement into thechannel 22 of thecap. yBy rotating table 17 several'revolutions duringthe time of deliveryof the cement an adequate distribution of the cementis insured. When slide 13 reaches the cap should be end of its returnmovement pin G8 Vof finger 67 has passed fingervO so that, at thebevginning of the next forward movement of the slide, finger 67 isthrown into cap-engaging'position. If, by any chance, no

51 will descend far enoughv to permit the locking bar 60 to enter notch59 of valve 32 and hold the valve in the position shown in Fig. 7until'aftci the pump piston has descended. ln this positioncommunication betweenv the pump and nozzle 25 is cut off by valve andthe passage 5S forms a coin- `munication between the pump and tube 41'so 4thatany cement in the pump above valve 32 may pass freely back intotube 4&3, thus preventing any material pressure' iii 'the pump whichmight tend to 4canse the iinprisoned cement to be forced out through thevarious packing glands or to cause a straining of the pump-actuatingpai-ts.`

By connecting the reservoir 45 with the pump body 29 and providing the'cylinderand-crown friction drive 4950 for the stirrer 48 only a singlefastening is necessary for enabling proper adjustment of all` the cementdelivering mechanism.

In the form shown in Fig. 10, the rotary table 17 is driven from a mainshaft 80, the can caps being placed on the table 17 in the, same mannerasin the other machine, and held thereon by a plunger 81, normally urgeddownward by a spring 8 2. Connectedto plunger 81 is a lever 83 having anotch 84 adapted to engage one arm of a belldelivered to table 17,plunger crank-lever 85 whenever plunger 81 descends as low as ispossibley when no cap is on the table. Lever 85 is actuated in onedirectionby a cam 86 and in the other by a spring S7. Connected to lever85, by a link S8, is a valve 89 which controls outiiow from a nozzle 90like nozzle 25. Nozzle 90 is the outlet-of a pump 91 connected to thecement reservoir 92 and provided with a piston 93 connected to'a lever94 actuated by a camrod 95 and cam 96.
